Hi Larry
I was one of the ones that asked I found this info out from Timken.
Could not find the dimensions on the stock bearings.
>From the Timken Catalog:
Sprite: ball bearing
FRONT WHEEL
Year Desc. Seal No. Bearing No.
58-71 inner 471192 7205
58-71 outer 7303
Sprite: roller bearing conversion
58-71 inner 471192 30205
58-71 outer 30303
Sprite REAR WHEEL
Year Desc. Seal No. Bearing No.
58-70 472164 207
Sprite Mk. IV CLUTCH RELEASE - ball bearing design replaces original
style carbon bearing
Year Desc. Seal No. Bearing No.
66-72 AU1715C
Here are the Dimensions.
inner
30205 bore:0.9843, OD:2.0472, Width:0.6398, C90lbf:1840, Kfactor 1.56
outer
30303 bore:0.6693, OD:1.8504, Width:0.6004, C90lbf:1770, Kfactor 2.05
inner
07097 Bore:0.9843, OD:2.0470, Width:0.5910, C90lbf:1570, Kfactor 1.45
outer
05066 Bore:0.6690, OD:1.8504, Width:0.5662, C90lbf:1440, Kfactor 1.64
I do not know what C90lbf or Kfactor means, I assume its some sort of
strength rating.
Reagards,
Peter S.
